He was found by the Turtles several years later, who asked him to serve as one of the witnesses at Krang's trial. Anemon pretended to be enslaving Eymo and only caring for strength over weakness, so Leonardo proposed that if one of them were able to physically defeat him, he would have to come with them.
During his final fight against Leonardo, Eymo was separated from Anemon, causing him to panic. Eymo returned and allowed him to defeat a deadly cloud-beast.
It was then revealed that Anemon was crushed by the guilt of accidentally killing his people, and that only Eymo's influence gave him the will to live. With the assurance that Eymo would come with him, he agreed to leave the planet and testify at the trial.
Along with the other witnesses, Anemon was threatened by the assassin Hakk-R during the trial, and had Eymo torn from his head in order to render him helpless. He survived the encounter and immobilized Hakk-R, allowing Donatello to intervene with a better offer. Afterwards, he and Eymo returned to their planet.
